What is centriprtal acceleration ? In which direction it acts ?

Explanation

### Step-by-Step Text Solution:

1. **Understanding Centripetal Acceleration**:
- Centripetal acceleration is the acceleration experienced by an object moving in a circular path. It is necessary for changing the direction of the object's velocity while maintaining a constant speed.

2. **Direction of Centripetal Acceleration**:
- Centripetal acceleration always acts towards the center of the circular path. This is because, as the object moves, its velocity vector changes direction, and the acceleration must be directed inward to facilitate this change.
